Citation 2 de-ice/anti ice question

[ehbuddy]

Some of these airplanes were built with the wet leading edge system like the Hawker's.

Is it effective? If you were on the approach with the system selected OFF and encountered icing and then selected the system ON how long does it take to shed the ice?

Re wet wing de ice system on Citations

I believe some 550s and maybe 500s were built with the weeping wing de ice system but I dont think a lot were constructed.

I have no personal experience with the system but believe it was a nightmare to maintain. A lot of tubes and valves etc and Id expect it would activate imediate on flicking the Cessna switch . The isoproponol would then weep out on the selected surface and attempt to do its deed.
Probably within seconds of activation if that was the question

I dont care what they say say about Cessna junk the Citation will always be my favorite. Well maybe after the Twin Otter.

[who me ?]

The Citation S II was the only verision of the Citation group which had a wet leading edge which I know of.

It is anti-ice systm therefore , in response to your question, about getting into ice on approach on final and then turning it on ? As this systems is anti-ice it needs to be activated prior to entering icing conditions. With these wet wing systems , there are a few operational limits, one being if forcast icing conditions are present, the fluid tank mush be completely full prior to takeoff.

If icing conditions are encountered with the anti ice system off, the fluid outlet ports will become blocked with ice, and become useless.

Thanks for the info.

I found some details on this type of system on the FAA site. It apppears that 'fluid management' becomes a big issue and you cetainly would not want to run out of it when you need it the most......
